ALAMEDA -- Raiders cornerback DJ Hayden missed the final eight games of his rookie season with a groin injury, and now he's officially going to miss at least five of his sophomore season with a foot injury he suffered during an offseason workout.

Oakland's first-round draft pick in 2013 was placed on the physically unable to perform list Tuesday after failing to convince coach Dennis Allen he'd be ready to go by the season opener.

The Raiders pared their roster to 75 players in advance of Tuesday's deadline by making moves with eight players.

The Raiders also waived wide receiver Juron Criner, a fifth-round draft pick in 2012 who failed to make much of an impact.

The Raiders have until Saturday afternoon to trim their roster to 53. Between now and that time, they host the Seattle Seahawks in their exhibition finale, which gives coach Dennis Allen and his staff one more chance to see their players in a game setting.
